In the residential district Kamiitsukomachi's old shopping district lies Hibikino Shop. This general store closed down after the grandfather owning it finally retired.
His three granddaughters, attached to it, and unwilling to let it disappear, decided to renovate it.
Hibikino Shop, loved by its community since 50 years, under the pressure of Yukari, the good for nothing of an eldest sister, became... an eroge store!
Hibikino Shop finally reopened.
A store of this size being too much for only three sisters to handle, and with only Yukari to know about this peculiar kind of products, they asked the second daughter's childhood friend Kurama Ren, our hero, to help them, as a part-time worker.
This is a story about the eroge industry from the perspective of a salesclerk.

Tsukikawa Shrine has become strangely infamous as a place that supposedly spreads misfortune - a rumor that Shizuki Yachiyo, the daughter of the head priest, is highly concerned about. When Ichitaro ends up living at the shrine for a while, he starts helping his childhood friend out on the job, and eventually, he realizes something.
While Yachiyo is a diligent, hard-working priestess, she doesn't actually seem to believe in the shrine's deities, or the effect of their charms, at all. She also doesn't smile as much as she used to, almost as if she's given up on all hope in life. Without any friends at school, she always appears to be rather lonely.
Then, one night...
Ichitaro wakes up sensing a strange presence, and finds Yachiyo perched on top of him, peering into his face. She looks almost like an entirely different person
"You know... I actually wish I could..."
The small priestess reveals to him her deepest feelings - her worries, and her hopes.
Now that she's opened up to him, and only him, Ichitaro feels like he must console her somehow.
"Dear gods, please tell me this is the right thing to do..."
"Yep!"
"...Huh?"
